Application August 13, 1938, Serial No. 224,814 4; @Taima (ci. nf-3s)` yThe invention relates to ornamental glass to be used as a decorative trimming and the process Vof making this glass.

Among the objects of the invention are first,

to provide anornamentalglass with a large` number of beautiful designs which may be varied by changing the mold, by changing the color of the glass itself and by changing the color of a material applied thereto; 'to use in the aforesaid l0 ornamental glass a low priced molded glass such as that used in the trade for leading, which has the characteristic that itis manufactured sub stantially of the thickness of ordinary window glass but with one or both surfaces of a roughcned or wavy form; toprovide a method of manufacturing this novel ornamental glass which is simple and economical.

The method of manufacture in a preferred form comprises the following. steps; first, a

` roughened surface of a molded glass of a desired design is coated with silver as in the manufacture of ordinary mirrors, second, the high spots are brushed to remove the silver therefrom, the size of the brushed-off areas being greater if the pressure on the brush is greater, to leave designs as viewed from the front which are related to the high spots ofthe rear surface of the glass; third, a shellac of any desired color is applied to the silvered surface to cover theyexposed transparencies, which gives a design as viewed from the front that is colored both by the color of the shellac selected and by the color of the glass itself; fourth, the back of the glass is finished by coating it with a rubber paint. In` a modification of the method, between the second and third steps; after the high spots are brushed to remove the silverand before the colored shellac is applied to the silvered surface, the latter is copper plated in order to produce amore durable and lasting ornamental glass.

irregular varying refracting structures whichl diffuse the light from the silvered surface and from the colored design to givea great variety of attractive light effectsf,

is still wet;

Referring to the drawing, in which the coatings are magnied:

Figure 1 is a rear view of a plate of molded glass showing circular convex protuberances with the front of therplate plane. l

Figure 2 is a section on line 2-2 of Figure 1. Figure `3 is a rear view after silvering which Figure 4 is a section on line 4-4 of Figure 3. Figure 5 is a rear view with the silver brushed l0 off to expose the high spots of the protuberances, the siivering being indicated in part.

Figure 6 is a section on the line 6-6 of Figure 5.

Figure 7 isa section similar to Figure 6 but 15 after a coating of red shellac has been applied to the rear surface.

Figure 8 is a similar section after a coating of rubber paint has been. applied to the rear surface. 20

Figure 9 is a frontview showing the circular designs in red shellac and the silver mirror indicated in part.

Figure 1o is a view similar to Figure 6 but Figure 11 is a front-view of a different design having green shellac as a backing.

Figure 12 is a front View, in whichthe glass is 30 yellow, the petals are green, and the center of the flower is yellow.

In one 'embodiment of my invention the method of manufacture is as follows: A glass plate 20 is molded to form a plurality of similar cir- 35 cular protuberances 2l in bas-relief having spherical surfaces on one side, the opposite side 22 being plane, as shown in Figures 1 and 2.

Next, the left side is silvered or mirrored with the usual coating 23 to completely cover the 40 surface as shown in Figures 3 and 4.

Then this irregular surface is brushed off while thesilvering 23 is still' fresh to leave circular transparent high spots 2l, the tops of which are in the saine plane, as shown in Figures 5 and 6.- 45 Itis clear that by increasing theppressure in brushing the circular designs areincreased in size and vice versa, to the same depth, so that the designs are easily increased ordecreased in A this manner. In case that irregular shapes are selected the designs themselves would obviously bevaried by varying the pressure on the brush.

In any case this is a very simple mechanical operation which is easily varied and exactly controlled.

vgive what may be called a living or vital quality to thecolored design. Light from the mirrored surface 23 is similarly reected and refracted. f

Figure illustrates a modification in which the back of the silvering 23 is covered with a copper-plate 30. This copper-plate 30 is applied in manufacture after the wetvsilvering 23 has been brushed off to expose the transparent designs 2| in bas-relief, and copper naturally-adheres only to the sliver, leaving .thebas-relief design exposed to directly receive the sheliac on the surface 2i of the plate 20.

In Figure l1 a green shellac 26 has been applied to the bas-relief design on the rear giving the eifect of a green sea with silvered peninsulas 23 projecting thereinto from the front.

In Figure 12 a yellow glass plate 21 has been used with the usual silver mirror 23 which is yellow-tinted as seen from the front, the design in .bas-relief being a flower. A green shellac 28 has been applied to the petals and a yellow shellac 29 to the center of the ower. Variations in color tlnts and hues are thus obtained.

' It is clear that one or both sides of a glass.

plate 2|) may be molded in any desired bas-relief designs, thecolor of the plate being. varied.

Having shown and described my invention it is clear that many variations can be made by -those skilled inthe art within the spirit and inga glass plate with one surface having any desired design in bas-relief, second, silvering this surface, third, brushing the high spots of the bas-relief design to remove the silver and pro duce a design in transparent glass, fourth, applying sheliac to cover this side of the glass, fifth,

applying sheliac to cover this side.- of the glass,

sixth, applying a rubber paint entirely covering the back.

3. An ornamental glass having one side moulded with predetermined portions thereof in basrelief, having the topsof the higher parts thereof in the same plane and forming any desired design, parts of the surface covered with silver silver, sheliac covering both the silver. and the uncoated high parts of the bas-relief, and a coating of rubber paint, the glass being of one color to produce retracted light of that color and the sheliac being of a different color selected to produce a color harmony between the two colors.
